These mutants are really very afraid of light, Shen Chao captured a mutant alive in the battle, grabbed its neck and dragged it to the sun to test it, but this mutant who was still struggling violently before immediately screamed as soon as he encountered direct sunlight.

Its screaming voice was very harsh, and it struggled very much, but for Shen Chao now, such a struggle was not much stronger than a 4 or 5-year-old child.

Under his strong control, this mutant could only leak into the sunlight, and was quickly killed by the sun, Shen Chao observed the whole process of the sunlight killing this mutant up close.

He grabbed the mutant with one hand and scanned the mutant with a multi-tool with the other. This allows it to use the medical procedure module on the universal tool to observe the superficial changes in the mutants and determine why they are so afraid of light.

As a result, the results of the scan on the multi-tool overturned his previous suspicions. On the surface, the mutant's surface skin has obviously undergone drastic changes under sunlight. It's like being corroded by a strong acid.

But this is just an illusion, and the real damage is happening in the body of the mutant. Ordinary sunlight is as lethal to this mutant as ultra-high-intensity radiation. But the damage doesn't come from some particular chemical reaction.

The mutant in Shen Chao's hands actually died in a desperate struggle between his own endocrine system and immune system. These two systems of mutants infected by the KV virus are very powerful, and their work efficiency is much higher than that of normal humans.

The rate of cell proliferation and excretion of mutant people is much higher than that of ordinary people. Virtually unaffected by aging. And when they are injured or sick, their immune system will quickly multiply various immune cells to help them fight the injury.

Often, these are good news for health. However, for these mutants, these traits of theirs have left a fatal flaw while enhancing their ability to survive and move.

After being exposed to ultraviolet rays, a large number of genetic information mutations will occur, and the cells will not be able to replicate themselves normally under sunlight and turn into cancer cells. It becomes a useless and even harmful part of the body. The newly multiplied cells become a burden to the body.

However, this can debilitate mutants at best, but it does not explain their sudden death in a short period of time. What really kills them is their own immune system.

When cancer cells are found in their own bodies, their immune systems immediately join in. Rapidly replicates a large number of immune cells, constantly trying to kill these cancer cells and restore bodily functions.

However, under the light exposure, a large number of these newly copied immune cells become cancer cells, and the immune system further increases the replication of various immune cells, thus forming a vicious circle.

In this way, the endocrine system and immune system of the mutant increase the consumption of bioenergy in the mutant human body in a geometric multiple, and finally the supply channels in the mutant human body cannot be supported, and the whole body collapses systematically.

That's why these mutants are so afraid of light, it's not performance art, and the lethality of sunlight on them is really significant.

The results of such an examination reminded Shen Chao of a very similar symptom he had seen in Starlink's public medical information. If it's the same type of work. Then he and his expedition should be immune to the KV virus here by now.

Due to an early incident, Starlink's standard booster is clearly effective against this type of virus. However, he will not risk taking off his helmet to test it himself, he is not a biologist after all, and he cannot draw conclusions about it, and such a professional identification still depends on professionals.

After cleaning up the scattered dozen or so mutated creatures, the sky was completely bright. The mutants are hiding in the building. Then it took them an hour and a half to drive through the city's passable passages. …,

The further you drive into the city, the smoother the road becomes. It can be seen that some roads have been artificially cleared for traffic. Come to think of it, the only one in the city who can do this now is Dr. Neville.

They slowly drove through the empty streets, past the once-thriving commercial streets and various buildings. Last night. Their scanning of other survivors in the city was in vain.

In the whole city, there is only the movie Robert . Dr. Neville's residence has signs of normal human life. This is in line with the plot of the movie.

After passing several famous landmarks, they drove to Dr. Neville's house. This is a very old three-story house. At first glance, it is late colonial style. Big living space and good location.

On the main plane, such a house alone costs millions of dollars. I can make my home here. It shows that Dr. Neville's career was already very successful before the crisis broke out.

According to the statement in the movie. Dr. Neville usually leaves his residence close to noon to go out hunting, gathering supplies, and securing the yàn body......

In the morning, Dr. Neville does some work like fitness and practice. So the doctor should still be at home at this point.

Parking the car on a nearby street, Shen Chao and they got out of the car. They avoided the mines they had detected last night and made their way from a safe area to the front door of Dr. Neville's house.

Shen Chao tried to knock on the door a few times, and immediately there was a dog barking from inside. Then there was the sound of panicked stairs climbing. Shen Chao's senses are so sensitive now, he almost doesn't need sonar goggles to understand the general situation behind the wall through the sound.

Dr. Neville grabbed a rifle from the weapons cabinet in the doorway and looked outside with the cat's eye on the door. After seeing Shen Chao and them, he hurriedly opened the door.

Upon seeing the three men outside the door, Dr. Neville, with a rifle in his hand, blinked as if he couldn't believe it, and he opened his mouth, but he didn't know what to say.

"Robert. Dr. Neville? In the end, it was Shen Chao who opened his mouth first, and as he spoke, he stretched out his right hand and made a gesture of shaking hands.

He could understand Dr. Neville's feelings, who had not seen a living person in 3 years, and then suddenly saw the three of them appear on his doorstep, and he would wonder if he was hallucinating. In particular, the three of them are all wearing "fancy costumes" that seem to be taken out of science fiction novels.

"I am! Dr. Neville replied sluggishly, and then, as if he had finally reacted, he put down the rifle in his hand and shook Shen Chao's hand.

He shook Shen Chao's hand with both hands, shook it very hard, and after making sure that he was indeed holding the hand of a living person, not air, he smiled very brightly. It was a very warm smile, and Shen Chao could feel the other party's excitement.

"Thank goodness you're really alive. Dr. Neville almost jumped up in excitement, the three men in front of him were definitely human despite their strange armor, and this was the best news he had received in three years.

"We heard your broadcast, but we don't think it's necessary to wait until noon to meet again......" Shen Chao briefly explained how he found him, he didn't say where he came from, now is not the time.

"Can we come in, Doctor?" Shen Chao stood at the door and asked. They still have a lot of explanation to do, and it's obviously much more appropriate to be in the house than standing on the porch.

"Oh, of course, welcome, all come in." When Dr. Neville heard Shen Chao's words, he suddenly reacted and immediately warmly invited them in. He said as he retracted the rifle that had been placed in the doorway. …,

"What do you drink?" I might have some tea or something......" Dr. Neville asked hurriedly as soon as he entered, looking at him for fear of treating him badly to his first guests in years.

"Doctor, then we can wait, we need to confirm whether we can be immune to the KV virus first......" Shen Chao declined the doctor's hospitality, these can wait, their primary goal is to find out if they can be immune to the virus here.

"But how can you not know if you're immune? Dr. Neville turned his head and wondered, it has been almost 3 years since the virus broke out, how can anyone not know if they are immune to the KV virus?

"We have never been exposed to the KV virus before, and on the way here, we have not taken off our chemical protective suits...... Shen Chao said, pointing to the armor on several of them.

"This is our blood sample, and we need you to help us test if our immune system is able to withstand the virus. With that, he motioned for Alice and Custer to bring out their blood samples, which they gave to Dr. Neville.

"Oh, that's right, follow me" Dr. Neville looked at the light outside the window at the three vials in his hand, and motioned for them to follow him. His tone was a little confused, but he still followed Shen Chao's request and led them in the direction of the real room.

At the top of the stairs, Dr. Neville still left his dog, and then he led Shen Chao and them to the passage in the basement, which was Dr. Neville's real room. Testing is currently only possible here.

Descending to the end of the stairs, Dr. Neville washed his hands and motioned for them to come in. He opened the door and entered the room and turned on the light.

After entering, he reminded Shen Chao that they should be careful not to break anything, and then immediately skillfully opened the computer and camera in the real room and began to record the scene in front of him.

"This is Dr. Robert Neville, September 4, 2012. I have 3 guests who have come out of the blue, and the visitor needs to be immunoverified to start the testing procedure. He said this to the camera as if he were talking to himself, and then he took the blood samples of the three people and began to test.

His underground room is not very large, only 5 or 60 square meters in size at most, and it is full of all kinds of real utensils, and there are several barrels of fuel in the corner.
